A man who gives something to another in mudarabah

Hammad said concerning a person who gives someone goods as mudarabah and values the goods at a thousand dirhams, and the other then sells them for nine hundred dirhams: The capital will be nine hundred dirhams.

Al-Hasan said concerning the case in which a person gives another goods as mudarabah and the two of them value them: The value at which the goods were assessed will count as the capital, and their own value carries no weight.

Tawus (may Allah have mercy on him) said: There is no harm in a man assessing the value of goods against another man and then giving them to him as mudarabah at that value.
